Armed clashes took in Wau State from late June 2016 to January 2019 between the Dinka-dominated Sudan People's Liberation Army (SPLA) and local opposition forces, consisting of tribal Fertit militias as well as fighters claiming allegiance to Riek Machar. It is unclear to what extent these rebels were actually part of the SPLM-IO or acting independently while using the SPLM-IO's name. The clashes resulted in the arrest of the state's governor, Elias Waya Nyipuoc, widespread death and destruction in the state capital, Wau town, and the displacement of up to 150,000 people.
